The arrangement of devices such as a vortex generator on the wing of an aircraft usually requires repeated wind tunnel tests in the design stage to determine the optimal arrangement to yield the best aerodynamic characteristics. ...[more]

Transonic buffet, an unsteady shockwave oscillation phenomenon that occurs at transonic flow speed, determines the upper limits of an aircraft’s flight envelope and causes undesirable vibration on an aircraft. It also has a considerable effect on a rocket’s payload vibration environment inside the fairing during launch. Optimizing the configuration of aircraft and launch vehicles using aerodynamic devices to improve aerodynamic characteristics and expand the corresponding flight range would make it possible to increase overall safety.
